The content emphasizes the importance of user feedback and outlines features related to Document Colour Tracking Dots, which are small dots embedded in prints that contain information about the printer and the printout. These dots are found in nearly all commercial color laser printers and can be decoded to reveal the printer's serial number, among other details. The text also highlights the capability of anonymizing printed documents to prevent tracking. For users interested in this technology, it references a research paper for citation and offers guidance on how to install

Last year, 37signals introduced two HTTP proxies: Thruster and Kamal-proxy, which have overlapping features. Thruster is designed specifically for serving Rails applications and is lightweight, effectively "wrapping" around a single application process. It’s ideal for quickly deploying proof-of-concept apps without the need for load balancing or zero-downtime updates. Users can easily set it up with minimal configuration by defining a TLS_DOMAIN for automatic SSL/TLS and using a simple command to launch their app

In an April Fools' joke post, Justin Le humorously addresses the challenges faced by Haskell enthusiasts when forced to write in other programming languages. He suggests that the concepts of Algebraic Data Types (ADTs) and Generalized Algebraic Data Types (GADTs) are so foundational that they can be adapted to various languages, despite potential quirks or unconventional methods. Le explains that ADTs consist of products (immutable structs) and sums, and emphasizes the importance of using appropriate patterns,

The article by Andrew Walsh, creator of openapi-devtools and Demystify, discusses the challenges developers face regarding API documentation. Poor or nonexistent documentation can severely hinder productivity, increasing frustration and errors. While documenting APIs is important, it can be complex and time-consuming, especially under tight deadlines. To address these issues, various solutions have emerged that automate API documentation. Some libraries, like drf-spectacular, infer API contracts from code structures, while frameworks like FastAPI and Huma generate Open

The content introduces Eventually Green Tests (EGT), an innovative software testing approach inspired by the concept of eventual consistency in distributed systems. EGT posits that failing tests will resolve themselves over time through various scenarios: either the code will align with the tests, the tested features may become obsolete, existing tests will become irrelevant due to major code base changes, or an entire application may be deprecated. A study from FAANG companies supports the approach, noting that 97% of failing tests either eventually pass or

The abstract reveals that the author discovered that the commonly accepted exponential dependence of resistivity on temperature in germanium is misleading. The author criticizes both their equipment and existing literature, deeming the effort a waste of time. In the introduction, the author discusses the concept of electron confinement in energy bands in germanium and explains that heating the material allows electrons to transition to conductive bands, which supposedly affects resistivity in an exponential manner, though the author dismisses the complexity of the theoretical background. The experimental

The author reflects on their experience with AI tools, particularly in coding and development. They first used AI in late 2022 and were initially impressed with its capabilities, especially for debugging. Over time, however, they noticed a decline in their own coding skills as they increasingly relied on AI integrations like GitHub Copilot in their workflow. By late 2024, the author decided to remove these AI tools, even though they still occasionally use AI and see its potential benefits for programmers. The author compares
